GIN ATTACHMENT.

T 0 all whom it may concern:

Be it known that I, EDWARD A. Rozmn, Sr, a citizen of the United States, and a resident of Sparta, in the county of Hancock, State of Georgia, have invented a new and useful Improvement in Gin Attach= ments, of which the following is a specification.

My invention is an improvement in gin attachments, and has for its object the provision of a simple device of the character specified for absolutely removing all of the motes and black specks in cotton during the operation of ginning, and for also removing earth stains, and which may be applied to the ordinary or usual gin without any material changes in the said gin.

In the drawings: Figure 1 is a vertical longitudinal section of the improvement; Fig. 2 is an enlarged perspective View of a port-ion of the brush; Fig. 3 is a similar view of the stationary brush; Fig. 4 is an enlarged vertical section of the improvement on the line of the brush.

In the present embodiment of the invention the case 1 of the gin is provided with the usual feed opening 2. Bars 3 are arranged transversely of the feed opening, and gin saw comprising a disk 4 provided with teeth 5 projects a portion of its periphery between each pair of adjacent bars.

The disks are secured to a common shaft 6 journaled in the frame, and spacing collars 7 are arranged between the adjacent disks. Each of the bars 3 is provided with a depressed or rearwardly curved portion 8 intermediate its ends, and a cylindrical brush 9 is secured on a shaft 10 journaled behind the shaft 6 and parallel therewith.

The improvement comprises a casing, box, or receptacle 11 arranged on the bottom of the case 1 between the shafts 6 and 10, and a plurality of tubes 12 extends upwardly from the box or casing between the said shafts and slightly above the level of the same. Each of the tubes is substantially rectangular in cross section, open at its top, and communicating with the box or casing at its bottom.

A pair of shafts 13 and 14 is journaled transversely of the case 1 near the top thereof, and another pair of shafts 15 and 16 is journaled transversely of the receptacle 11. All of the shafts 13 to 16,.inclusive, are

parallel and in vertical alinement, and each shaft is provided with a plurality of toothed wheels 17.

The wheels 17 on each shaft are arranged alternately with respect to the wheels on the other member of the pair, and the wheels on the shafts l3 and 16 register or are in alinement, as are also the wheels on shafts 14 and 15. Each registering pair of wheels 17 is also in alinement with a tube 11.

The shafts l3 and 14 are journaled in bearings 18 on the inner face of the top of the case 1, and sprocket wheels 19 and 20 are secured to the respective ends thereof. A sprocket chain 21 connects wheel 20 with a sprocket wheel 22 on the adjacent end of shaft 16, and a chain 23 connects wheel 19 with a sprocket wheel 24 on the adjacent end of shaft 15.

A sprocket wheel 25 is secured to one end of shaft 14, and a chain 26 connects the said wheel with a similar wheel 27 on the adjacent end of shaft 15. Shaft 15 is provided with a worm wheel 28 outside of the wheel 24, and a worm 29 on a shaft 30 meshes with the said worm wheel to drive the shafts. The worm shaft 30 is driven in any suitable manner, as are also the shafts 6 and 10.

An endless belt is supported on each pair of registering wheels 17 Each of the said belts in composed of spaced flexible steel bands 31 and 32 connected at spaced intervals by eyelets 33. Bristles 34 are arranged transversely between the plates and extend beyond each side thereof, as shown in Fig. 2. A band 35 of tape, of cotton, or like fabric material is arranged between one of the bands 31 or 32, the latter in the present instance, and the bristles. Each of the said endless bands is constructed as follows. The bristles are laid in glue on the band 35, the glue being applied to the band, and the bristles laid crosswise thereon. The steel bands are then laid, and the eyelets are placed, securing the parts together and also serving as openings for engagement by the teeth of the wheels 17. The wheels thus move the belts positively.

At the top of each of the tubes 12 the device shown more particularly in Fig. 3 is arranged. The said device comprises a holder consisting of a tube or shell 37 secured transversely of the tube between the side walls thereof and near the front runs of the belts. It will be noticed that the front side of each tube is higher than the rear side, the rear side being cut away on a bevel, as indicated at 88.

A strip 39 of suitable material is doubled upon itself and upon a transversely arranged tuft 40 of bristles, and the ends of the strip are inserted in the holder and held in any suitable manner. It will be noticed that the runs of the belts pass on opposite sides of the holder 37, the front run of each belt passing close to the holder.

A port-ion of each disk 4: projects between two adjacent tubes, and an inspection of Fig. 4: will show that both sides of the disks are engaged by the edge of a belt, that is, by the extended ends of the bristles. In addition, each disk is engaged on both sides by the ends of the bristles 40. The engagement of the bristles 40 is at the edge of the saw, so that the teeth are brushed by the said bristles. Both runs of the belts engage the teeth, and each saw is engaged in two places by the front runs and in two places by the rear runs, and in one place by the bristles 40.

In operation, the cotton is fed in the usual manner and the seeds are removed as the cotton is drawn through between the bars, the seeds falling from the ends of the bars through the opening a1 between the said front ends and the front of the case 1. The belts travel very slowly, probably two feet per minute, and as they move they carry away the motes, specks and dirt that are combed from the lint by the bristles before the said lint is removed from the saws by the brush 9. The said impurities are drawn down the tubes and removed by the exhausting apparatus. The cotton is rubbed, combed or brushed between the moving brushes, that is, the belts, and the stationary brushes, that is, the bristles 40. The brushes are especially effective, since they operate on the smallest possible quantities of cotton possible, namely, the little tufts drawn through the bars by the teeth of the disks.
